Repotting "Cactus"
As a representative of desert plants, the cactus is loved by gardening enthusiasts for its unique shape and super strong vitality. To keep the cactus in your home growing vigorously, it is particularly important to master scientific repotting techniques. With proper substrate configuration and maintenance management, it is entirely possible to keep the cactus growing for more than 10 years and blooming stunning flowers.
One, Key Points of Repotting Cactus
1. Timing of Repotting
It is recommended to perform the repotting operation every 2-3 years in spring, when the roots appear at the bottom of the pot or the diameter of the ball exceeds 2/3 of the pot opening, which is the best time for repotting.
2. Substrate Proportion Scheme
Using the golden ratio of humus soil: coarse river sand: vermiculite = 5:3:2, it not only ensures nutrient supply but also strengthens drainage performance. Adding 10% bone meal can enhance the calcium supplement and promote the full development of the ball.
3. Pot Upgrade Strategy
The diameter of the new pot should be 5-8 cm larger than the original pot, preferably a red clay pot with strong breathability. Place a 3cm thick layer of broken tiles at the bottom of the pot as a drainage layer to prevent waterlogging and root rot.
Two, Advanced Maintenance Technology Analysis
1. Light Control Scheme
Ensure 6 hours of direct sunlight every day, and shade 30% at noon in summer. Use the 180° regular pot rotation method to ensure that the ball is evenly lit to avoid abnormal growth.
2. Smart Watering System
Spring and autumn 15 days/time, summer 10 days/time, and winter water cutoff maintenance. Use the "pinching pot method" to judge: when the weight of the pot soil is reduced by 2/3, water slowly along the pot wall.
3. Nutrient Supplement Skills

Surface铺设volcanic rock particles, which can decorate and slowly release minerals. During the growing season, add phosphorus and potassium fertilizer (N-P-K=5-15-15) every month, diluted 1000 times and watered at the root.
Three, Long-term Maintenance Management Guide
Regularly check whether the base of the ball is lignified and cut the top for propagation if signs of aging are found. Maintain ventilation in the environment and keep the temperature above 8℃ in winter for overwintering. Through systematic maintenance and management, not only can the cactus grow healthily for more than 10 years, but also enjoy beautiful flowers with a diameter of up to 15cm in late spring and early summer.
